SJB Review of When the Cat's Away
Chacun Cherche Son Chat
(France, 1996); released in the US under the title When the Cat's Away
Seen on 22 June 1997 with Tony for $8 at the Quad Cinema.
Based on a true incident, director Cedric Klapish discovers that the search for a lost cat in the Bastille section of Paris turns up a lot more than you might think. Chloe (Garance Clavel) lives with Michel (Olivier Py), who really doesn't want to look after Gris-Gris (Arapimou), her black cat. She eventually finds Madame Renee (played by chatty non-actor Renee Le Calm), who has at least a half-dozen cats and several dogs in her charge. Imagine Chloe's horror when she returns to discover that Gris-Gris has flown the coop. Madame Renee springs into action, though, with her network of other septuagenarian friends in their Bastille neighborhood.
As Chloe--a make-up assistant--searches for Gris-Gris, she undergoes a change. She becomes immersed in her neighborhood and becomes part of it. It is impossible to overlook the forces destroying the personality fabric of the neighborhood--evictions, demolitions, and gentrification. As we are treated to a view of the rooftops of Paris, large cranes loom over the neighborhood. At one point the camera lingers as a giraffe-like bulldozer eats away at the top portion of a church it is destroying. Chloe's transformation is complete as she runs into a work acquaintance--who has just opened a trendy shop--while searching for her cat with Madame Renee and another crony. The new shop owner looks at Chloe's friends askance while then loudly criticize the store and its wares ("Who would pay 800 francs for a metal bra?").
Most urban dwellers can empathize with this Parisian neighborhood's woes; the march of realty development and how it makes irrevocable changes is a universal phenomenon, and urbaphiles everywhere will sadly recognize "the beginning of the end" as it is shown here. The camera works mainly as an onlooker. Chloe's loneliness is evident as she watches others have love lives--her roommate Michel features a new boyfriend every week, people at bars have each other, while men and women she doesn't want hit on her. But, as Chloe becomes a real part of the neighborhood, she begins to discover that happiness can be found right there in your own arrondissement.
NOTE: Watch carefully for the hilarious depiction of Claire's vacation. If you turn away or blink, you'll miss it for sure!

Save $300 On The 14-inch LG Gram Laptop
The LG Gram is getting its Black Friday sale a bit early. Right now, you can save $300 on the LG Gram from Amazon. Bringing the price down to just $1199.
This particular model is the 14T990-U.AAS8U1. Which comes with a 14-inch touchscreen. Along with an Intel Core i7-8565u processor, 16GB of RAM and 512GB of storage. This is all powered by a 72Wh battery inside. Which is going to keep this laptop running all day long – we're talking double-digit hours!
Now what makes the LG Gram, the Gram, is how powerful and lightweight it is. It weighs in at just two and a half pounds. That's a good pound lighter than most other Ultrabooks on the market.
Advertisement
Now the LG Gram is a pretty powerful machine, as you can tell by the specs. But it gets even better.
You can use the LG Gram as a tablet, and draw in different apps thanks to the Wacom pen that is included. Since it's a 2-in-1, you can fold the screen back and use it like a gigantic tablet. Which might appeal to some.
There is also support for Windows Hello, allowing you to login to your computer much easier than ever before.
Advertisement
The big reason why the LG Gram is so popular, is because of how light it is, while still being very powerful. And that is the case here. Now this isn't going to rival a gaming laptop from Razer or MSI, but it is going to get some work done. With that Intel Core i7 and 16GB of RAM under the hood.
Not to mention the pretty impressive battery life that most LG Gram laptops offer.
You can pick up the 14-inch LG Gram in this Black Friday sale from Amazon by clicking here. But you'd better hurry, as this sale won't be around for long.

--- title: 'Gapminder: GDP Per Capita' author: Darrick Sturgeon date: '2018-06-14' slug: gapminder-gdp-per-capita categories: - data visualization tags: - ggplot2 - R description: Desc hacker_news_id: '' lobsters_id: '' meta_img: /images/image.jpg ---
Here we take a look at country GDP per capita across different continents from 1950 to present.
gapm <- gapminder
gapm_gdpextrema <- gapm %>%
group_by(continent, year) %>%
filter(gdpPercap == max(gdpPercap) | gdpPercap == min(gdpPercap)) %>%
mutate(extrema = factor(case_when(gdpPercap == max(gdpPercap) ~ 'max',
gdpPercap == min(gdpPercap) ~ 'min'))) %>%
arrange(continent, country, year, gdpPercap)
gapm_gdpextrema_notasia <- gapm_gdpextrema %>% filter(continent != 'Asia')
gapm_gdpextrema_asia <- gapm_gdpextrema %>% filter(continent == 'Asia')
p1 <- ggplot(gapm_gdpextrema_notasia, aes(x = year, y = gdpPercap, color = continent)) +
geom_point(alpha = 0.5) +
geom_line(stat = "smooth", method = "loess", se = FALSE, alpha = 0.2) +
geom_point(data = gapm_gdpextrema_asia, alpha = 1) +
geom_smooth(data = gapm_gdpextrema_asia, method = 'loess', se = FALSE, alpha = 1) + facet_wrap(~extrema)
p1
This is a time series plot with loess fit curve.
GDP for many countries spanning the continents. Here we focus on the extrema of GDP on different continents.
Readers interested in economic history.
I’m trying to highlight the stark pattern of Asia’s highest GDP in comparison with the other continents, dropping quickly from ~1950-80
Looking for trends across time, each dot is a sample or data point at a given time, we can infer that there is some continuity between them because it is a measurement of the same thing.
For time series data, it’s important to highlight differences over time. If each country has just about the same trend, such as on the right with min gdp, the result is less interesting and it may take more words to explain what is interesting about the comparison. On the left, the reader’s eye may already be drawn to Asia, but pulling it further makes the point clear.
bar charts are sometimes used to highlight differences in individual time points. If the trend over time is relevant but you want to illustrate differences in magnitude between classes being compared, it can be better to use a bar chart. you do run the risk of cluttering, it would not work well in this case with so many time points and classes.
In other times, people omit dots and simply plot lines which connect. In this case, since the plot is of gdp extrema (min/max), we may not want to imply continuity through a line plot. Line plots are better for measurements of the same thing so we don’t unecessarily imply the same country is on top during these periods.
I split the data between asia and not asia in order to change the relative transparency of the lines. This makes the data from asia pop out for the eye much more. The rest is simple use of geom_point and geom_smooth with se=False to not clutter the graph with error margins.

for creating groups of similar looking aircraft types;
Doc8643.txt
, the official list of ICAO aircraft type codes;
Obj8DataRefs.txt
, a mapping list for replacing dataRefs in .obj

A related group is declared simply by a line of ICAO a/c type codes read from the file. Internally, the group is just identified by its line number in related.txt
. So the group "44" might be "A306 A30B A310", the Airbus A300 series.

PSALMS 143
A psalm written by David.
1 Yahweh, hear me while I pray to you!
Because you are righteous
and because you faithfully do what you have promised,
listen to what I am pleading for you to do for me.
2 I am one who worships you;
do not judge me
because you do not consider anyone to be completely innocent.
3 My enemies have pursued me;
they have completely defeated me.
It is as though they have put me in a dark prison
where I have nothing good to hope for.
4 So I am very discouraged in my inner being;
I am very dismayed.
5 I remember what has happened previously;
I meditate on all the things that you have done;
I consider all the great deeds that you have performed.
6 I lift up my hands to you while I pray;
I want very much to be with you as much as I would thirst for water in a vast wilderness.
7 Yahweh, I am very discouraged,
so please answer me right now!

I pray to you;
show me the things that I should do.
9 Yahweh, I have gone to you for you to protect me,
so rescue me from my enemies.
10 You are my God;
teach me to do what you want me to do.
I want your good Spirit to show me the right things to do.
11 Yahweh, restore me when I am close to dying as you promised to do
because you are righteous!
12 I am one who serves you;
so because you faithfully love me as you promised to do,
kill my enemies
and get rid of all those who oppress me.

I've continued my exploration of the .NET Framework tools. Today, the time came for SoapSuds.exe and MgmtClassGen.exe.
The first one is interesting, because SoapSuds.exe is simply a driver around a couple of classes called SoapSudsCode
and SoapSudsArgs
. Now, that by itself isn't anything out of the ordinary. What is interesting, though, is that both of these classes are not defined inside SoapSuds.exe or the .NET framework libraries, but instead in a little known assembly called, you guessed it, SoapSudsCode.dll.
So what? Well, I found prety intriguing the fact that this assembly is not installed anywhere on the filesystem but the GAC. Yep. Nowhere else. Now, I'm not quire sure why they went through all this trouble. Truth is, there's not much magic going on inside SoapSudsCode either; it's basically a large driver around the MetaData
class in the System.Runtime.Remoting.MetadataServices.MetaData
namespace.
MgmtClassGen.exe is actually a lot simpler. The entire application consists essentially of some code to parse the arguments and a call to the GetStronglyTypedClassCode()
method of the System.Management.ManagementClass
class.
All of this outlines one of my favourite things in .NET: Quite a few bunch of the development tools we use daily are nothing more than simple wrappers around functionality already provided in the base class libraries. It's just so rich! And it's all functionality you could take advantage of if you were to build your own tools!

These changes, proposed for September 2012, are intended to raise expectations for further improvement in the performance of these schools, for the benefit of children, parents and carers.
Inspection reports will provide a clear assessment of how children are doing in the context of their age and ability. They will be based on observations of work, taking into account starting points and a school’s record of pupil progress.
Read the consultation:
Introducing a new framework for inspecting non-association independent schools.
The key inspection judgments proposed are:
-
overall effectiveness
-
pupils’ achievement
-
pupils’ behaviour and safety
-
quality of teaching
-
quality of the curriculum
-
provision for pupils’ spiritual, moral, social and cultural development
-
provision for pupils’ welfare, health and safety
-
leadership and management
In view of the diversity in size and nature of independent schools Ofsted is seeking to consult as widely as possible to gain the views of all interested parties on the proposals.
Ofsted Director of Education and Care, Jean Humphrys said:
The quality of teaching is the key driver of school improvement. One of the main findings from Ofsted inspection in this sector is that the quality of teaching in non-association independent schools tends to be competent but seldom inspiring.
It is vital that our inspection is incisive and rigorous, and that judgments are fair, clear and helpful to a school’s further development. With these new arrangements we will focus more sharply on what makes teaching truly effective.
The proposals build on the current arrangements for inspection. Ofsted will continue to use a 4 point scale to make qualitative judgements. Detailed grade descriptors will seek to provide more consistency, openness and transparency and encourage independent schools to strive further for improvements to the quality of provision.
Ofsted currently gives independent schools 2 days’ notice of their education inspection but for inspection of care in boarding and residential special schools no notice is given. Ofsted intends to adopt a similar system for the education inspection of independent schools. Pupils, parents and carers have told Ofsted that inspection without notice is important as it lets the inspectors see the school as it really is.
The views of the pupils themselves, as well as parents, carers, staff and local authorities who use the services of independent schools are highly valued by inspectors who follow up the issues they raise. These views will continue to be an important feature of inspection.
Despite recent improvement, the biggest single weakness in non-association independent schools remains the high proportion of schools (12%) which do not have sufficiently robust arrangements for safeguarding pupils’ welfare, health and safety. Ofsted will continue to check that secure and robust arrangements are made to provide a safe environment for children. It is therefore proposed to retain the separate judgement for pupils’ welfare, health and safety.
Additional proposals put forward for consultation cover children’s homes offering education, focussing on the quality of education where it is weakest: for looked after children in independent children’s homes which are registered education providers.
Among independent children’s homes which are registered education providers there is a comparatively lower proportion that makes good or outstanding educational provision. The new framework will focus on the educational progress and achievements of looked after children and look critically at what schools are doing to close the gap between their achievements and other pupils.
Following the consultation, Ofsted intends to test the new inspection arrangements in pilot inspections, before introduction in September 2012.
Ofsted inspects all non-association independent schools in England. These comprise around half of more than 2,000 independent schools. The remainder is inspected by the independent inspection bodies, Independent Schools Inspectorate (ISI), School Inspection Service (SIS) and Bridge Schools Inspectorate (BSI).
Notes to editors
-
Read the consultation and questions,
The new framework for the inspection of independent schools.
The public consultation runs for 12 weeks from 24 January 2012.
-
Ofsted seeks the widest possible range of views from those who have an interest in independent schools, in order to ensure that the inspection framework takes proper account of the needs and circumstances of all interested parties.
-
The main purposes of Ofsted’s framework for inspecting independent schools are: to check and report on the school’s compliance with the Education (Independent Schools Standards) (England) Regulations 2010; produce an evaluative report which informs the school, parents, pupils, and wider community about the quality and impact of the school’s provision; and to bring about school improvement.
-
Whilst the Independent Schools Standards will remain, the Department for Education is revising the regulations which underpin them, and these will be the subject of separate consultation. The outcome will inform the specific details of Ofsted’s evaluation schedule for the inspection of independent schools.
-
The government is revising the regulations for independent schools with the intention that they will be simplified for September 2012. Ofsted’s instruments and guidance for inspectors and schools will take account of these changes
-
The Independent schools framework consultation questions are as follows:
-
To what extent do you agree or disagree that inspectors should make a judgement on pupils’ achievement?
-
To what extent do you agree or disagree that inspectors should make a judgement on pupils’ behaviour and safety?
-
To what extent do you agree or disagree that Ofsted should make separate key judgments on the quality of teaching and the quality of the curriculum in an independent school inspection?
-
To what extent do you agree or disagree that inspectors should make a discrete judgment on pupils’ spiritual, moral, social and cultural development?
-
To what extent do you agree or disagree that Ofsted should retain a separate key judgement on safeguarding pupils’ welfare, health and safety in an independent school inspection?
-
To what extent do you agree or disagree that Ofsted should introduce a judgement on leadership and management for independent schools?
-
To what extent do you agree or disagree with Ofsted’s proposed approach to the inspection of smaller children’s homes in national or regional group providers?
-
To what extent do you agree or disagree with Ofsted’s proposal to inspect educational provision in independent children’s homes without notice?
-
Do you wish to make any other observations about the proposals for change in the consultation document?
Ofsted has already changed the frequency of inspection so that all mainstream independent schools which have met the regulations and been judged ‘good or outstanding’ will now, from September 2011, be inspected only once in a 6 year period.


What is Carbon Monoxide (CO)?
Carbon monoxide (CO) is a colorless, odorless, and tasteless gas that is slightly less dense than air. It is toxic to humans and animals when encountered in higher concentrations, although it is also produced in normal animal metabolism in low quantities, and is thought to have some normal biological functions. In the atmosphere it is spatially variable, short lived, having a role in the formation of ground-level ozone. Carbon monoxide consists of one carbon atom and one oxygen atom, connected by a triple bond that consists of two covalent bonds as well as one dative covalent bond.
Carbon monoxide is produced from the partial oxidation of carbon-containing compounds; it forms when there is not enough oxygen to produce carbon dioxide (CO2), such as when operating a stove or an internal combustion engine in an enclosed space. In the presence of oxygen, including atmospheric concentrations, carbon monoxide burns with a blue flame, producing carbon dioxide. Coal gas, which was widely used before the 1960s for domestic lighting, cooking, and heating, had carbon monoxide as a significant fuel constituent. Some processes in modern technology, such as iron smelting, still produce carbon monoxide as a byproduct.

[gecode-users] model with float variables sometimes hangs during search
Kurt Van Den Branden
kurt.vandenbranden at agfa.com
Wed Apr 15 15:59:41 CEST 2015
hi,
I have a Gecode model that uses float variables.
I use a BAB searchengine with a Search::TimeStop object to interrupt the
search when it takes too long.
I noticed that when the model is created with certain parameters, the
search isn't interrupted at the requested timelimit.
it either continues a lot longer than allowed, or it doesn't stop at all.
in these cases, the debugger shows that it's the method Space::status that
doesn't return sometimes.
it keeps on propagating and never stops.
I haven't been able to reproduce this with a limited test model yet.
Does anybody have tips on what could cause this problem?
Kind Regards,
Kurt Van Den Branden | Agfa Graphics

1.4 Remember how to compile?
gcc -std=c99 -pedantic -Wall -Wextra -ftrapv -ggdb3 -o programname programname.c
1.5 Preprocessor stuff like if-def
The preprocessor deals with all the lines that you start with an octalthrope or hash mark: #
The preprocessor lets you define symbols, macros, and include files.
1.5.1 Multiple Files?
How does stdio.h work?
It defines definitions, macros, and prototypes for the stdio library. The linker will link your executable to that library that was already compiled.
.h files help us organize C programs by including definitions for the object files and libraries that we will create.
Libc or glibc contains the implemention of those definitions. libc.so.6 => /lib/x8664-linux-gnu/libc.so.6 (0x00007f919f994000)
libc is composed of many .c files compiled into .o object files and then combined into a library. A library is like an executable that other executables rely on for code. malloc is defined in malloc.c and has a malloc.h file!
Typically if I make a library I will make a .h file so the definitions can be shared with other .c files. But the implementation of the functions will go into a .c file that includes that .h as well.
- main.c
- #include <stdio.h>
- #include "library.h"
- relies on library.o
- library.c
- #include "library.h"
- makes library.o
- library.h
- defines functions and definitions from library.c
1.5.2 Example
This is a useful function to check if scanf read 1 or more elements and didn't read EOF.
#include "checkinput.h" #include <stdio.h> #include <stdlib.h> /* checkInput: given the result of scanf check if it * 0 elements read or EOF. If so exit(1) with a warning. * */ void checkInput(int err) { if (!err || err == EOF) { printf("\nInvalid input!\n"); exit(1); } }
// Have a guard to ensure that we don't include it multiple times. #ifndef _CHECKINPUT_H_ /* checkInput: given the result of scanf check if it * 0 elements read or EOF. If so exit(1) with a warning. * */ #define _CHECKINPUT_H_ void checkInput(int err); // a prototype! #endif
#include "checkinput.h" #include <stdio.h> #include "checkinput.h" #include "checkinput.h" #include "checkinput.h" #include "checkinput.h" // void checkInput(int err); // a prototype! int main() { int input; checkInput(scanf("%d", &input)); puts("Good Input!"); }
- Compiling Multiple Files Easy Mode
We can put all our .c files on the same line and compile them all at once! This is handy. But quite limiting.
We can't parallel compile. We can't use all our cores. We can't interupt compilation.
# build checkinput-driver gcc -std=c99 -pedantic -Wall -Wextra -ftrapv -ggdb3 \ -o checkinput-driver checkinput-driver.c && \ ( echo YES | ./checkinput-driver || \ echo 100 | ./checkinput-driver )
BOTH FILES
# build checkinput-driver gcc -std=c99 -pedantic -Wall -Wextra -ftrapv -ggdb3 \ -o checkinput-driver checkinput-driver.c \ checkinput.c && \ ( echo YES | ./checkinput-driver || \ echo 100 | ./checkinput-driver )
Invalid input! Good Input!
- Compiling Multiple Files with Linking
OK now we compile it. The main is the last to compile and it needs all the .o files.
All the .c files that don't contain main need to be compiled to object files. Use the -c flags to do this.
# build checkinput.o gcc -std=c99 -pedantic -Wall -Wextra -ftrapv -ggdb3 \ -c checkinput.c file checkinput.o # build checkinput-driver and link it to checkinput.o gcc -std=c99 -pedantic -Wall -Wextra -ftrapv -ggdb3 \ -c checkinput-driver.c file checkinput-driver.o gcc -std=c99 -pedantic -Wall -Wextra -ftrapv -ggdb3 \ -o checkinput-driver checkinput-driver.o \ checkinput.o file checkinput-driver
checkinput.o: ELF 64-bit LSB relocatable, x86-64, version 1 (SYSV), with debug_info, not stripped checkinput-driver.o: ELF 64-bit LSB relocatable, x86-64, version 1 (SYSV), with debug_info, not stripped checkinput-driver: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/l, for GNU/Linux 3.2.0, BuildID[sha1]=a0d9427bff4f04c1475aa889bce881e4a5b7fb31, with debug_info, not stripped
- If you want some translation :-)
- ELF - Executable and Linking format
- relocatable - you can link it
- shared object - relocatable and executable
- LSB - little endian/least significant bit
- x86-64 - 64 bit x86 processor
- version 1 (SYSV) - version 1 of ELF System V Unix spec.
Test drive it
echo | ./checkinput-driver # bad echo X | ./checkinput-driver # bad echo 1 | ./checkinput-driver # good echo -1 | ./checkinput-driver # good
Invalid input! Invalid input! Good Input! Good Input!
Now let's see how it is linked!
ls -l ./checkinput-driver ls -l /lib/x86_64-linux-gnu/libc-2.27.so ldd ./checkinput-driver
-rwxrwxr-x 1 hindle1 hindle1 38472 Mar 19 11:31 ./checkinput-driver -rwxr-xr-x 1 root root 2030544 Apr 16 2018 /lib/x86_64-linux-gnu/libc-2.27.so linux-vdso.so.1 (0x00007ffe69d2b000) libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f07380e1000) /lib64/ld-linux-x86-64.so.2 (0x00007f07386d4000)
- syscalls (read, write, gettimeofday) and libc (libc is stuff like stdio.h)
- If you want some translation :-)
1.5.3 Linking to libraries
`math.h` includes fun functions like cos and tanh.
Math.h, part of the C stdlib, is distributed as a seperate library. Not all computers have floating point numbers so why bother compiling floating code for them?

Larger programs link to lots of libraries.
ldd `which xterm`
linux-vdso.so.1 (0x00007ffe7eede000) libXft.so.2 => /usr/lib/x86_64-linux-gnu/libXft.so.2 (0x00007fdfa84ae000) libfontconfig.so.1 => /usr/lib/x86_64-linux-gnu/libfontconfig.so.1 (0x00007fdfa8269000) libXaw.so.7 => /usr/lib/x86_64-linux-gnu/libXaw.so.7 (0x00007fdfa7ff5000) libXmu.so.6 => /usr/lib/x86_64-linux-gnu/libXmu.so.6 (0x00007fdfa7ddc000) libXt.so.6 => /usr/lib/x86_64-linux-gnu/libXt.so.6 (0x00007fdfa7b73000) libX11.so.6 => /usr/lib/x86_64-linux-gnu/libX11.so.6 (0x00007fdfa783b000) libXinerama.so.1 => /usr/lib/x86_64-linux-gnu/libXinerama.so.1 (0x00007fdfa7638000) libXpm.so.4 => /usr/lib/x86_64-linux-gnu/libXpm.so.4 (0x00007fdfa7426000) libICE.so.6 => /usr/lib/x86_64-linux-gnu/libICE.so.6 (0x00007fdfa720b000) libutempter.so.0 => /usr/lib/x86_64-linux-gnu/libutempter.so.0 (0x00007fdfa7008000) libtinfo.so.5 => /lib/x86_64-linux-gnu/libtinfo.so.5 (0x00007fdfa6dde000) libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007fdfa69ed000) libfreetype.so.6 => /usr/lib/x86_64-linux-gnu/libfreetype.so.6 (0x00007fdfa6739000) libXrender.so.1 => /usr/lib/x86_64-linux-gnu/libXrender.so.1 (0x00007fdfa652f000) libexpat.so.1 => /lib/x86_64-linux-gnu/libexpat.so.1 (0x00007fdfa62fd000) libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007fdfa60de000) libXext.so.6 => /usr/lib/x86_64-linux-gnu/libXext.so.6 (0x00007fdfa5ecc000) libSM.so.6 => /usr/lib/x86_64-linux-gnu/libSM.so.6 (0x00007fdfa5cc4000) libxcb.so.1 => /usr/lib/x86_64-linux-gnu/libxcb.so.1 (0x00007fdfa5a9c000) libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007fdfa5898000) libbsd.so.0 => /lib/x86_64-linux-gnu/libbsd.so.0 (0x00007fdfa5683000) /lib64/ld-linux-x86-64.so.2 (0x00007fdfa8973000) libpng16.so.16 => /usr/lib/x86_64-linux-gnu/libpng16.so.16 (0x00007fdfa5451000) libz.so.1 => /lib/x86_64-linux-gnu/libz.so.1 (0x00007fdfa5234000) libuuid.so.1 => /lib/x86_64-linux-gnu/libuuid.so.1 (0x00007fdfa502d000) libXau.so.6 => /usr/lib/x86_64-linux-gnu/libXau.so.6 (0x00007fdfa4e29000) libXdmcp.so.6 => /usr/lib/x86_64-linux-gnu/libXdmcp.so.6 (0x00007fdfa4c23000) librt.so.1 => /lib/x86_64-linux-gnu/librt.so.1 (0x00007fdfa4a1b000) libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007fdfa467d000)
See! Lots of libraries!
1.5.4 Example Datastructure
Let's make a brief data structure about one of my favourite topics: cool bears.
#define _POSIX_C_SOURCE 200809L // <-- needed for strdup #include "coolbears.h" #include <stdio.h> #include <stdlib.h> #include <string.h> // hiding struct details from other programmers // I DONT TRUST THEM. Especially Hazel ;-) (don't tell hazel) struct coolbear_t { char * name; float temperature; }; CoolBear createCoolBear(char * name, float temperature) { CoolBear coolbear = malloc(sizeof(*coolbear)); coolbear->name = strdup(name); coolbear->temperature = temperature; return coolbear; } void freeCoolBear(CoolBear coolBear) { if (coolBear == NULL) { abort(); } if (coolBear->name != NULL) { free(coolBear->name); } free(coolBear); } char * getNameCoolBear(CoolBear coolbear) { return coolbear->name; } float getTemperatureCoolBear(CoolBear coolbear) { return coolbear->temperature; } // NO MAIN!
// Have a guard to ensure that we don't include it multiple times. #ifndef _COOLBEARS_H_ /* checkInput: given the result of scanf check if it * 0 elements read or EOF. If so exit(1) with a warning. * */ #define _COOLBEARS_H_ struct coolbear_t; // Forward declaration -- I am not sharing details! typedef struct coolbear_t * CoolBear; // Struct point as type CoolBear createCoolBear(char * name, float temperature); // a prototype! void freeCoolBear(CoolBear coolBear); // a prototype! char * getNameCoolBear(CoolBear coolbear); // a prototype! float getTemperatureCoolBear(CoolBear coolbear); // a prototype! #endif
#include "coolbears.h" #include <stdio.h> int main() { CoolBear ziggy = createCoolBear("Ziggy",-23.0 /* C */); CoolBear kevin = createCoolBear("Kevin",-32.0 /* C */); CoolBear coolest = (getTemperatureCoolBear(ziggy) < getTemperatureCoolBear(kevin))? ziggy : kevin; printf("The coolest bear is %s\n", getNameCoolBear( coolest )); // // we actually don't know about name so we can't reference it below // printf("The coolest bear is %s\n", coolest->name ); freeCoolBear(ziggy); freeCoolBear(kevin); }
Compile it. -c the coolbears.c to make coolbears.o and then compile coolbears-driver.c
coolbears-driver.c has no clue how to access
# build coolbears.o gcc -std=c99 -pedantic -Wall -Wextra -ftrapv -ggdb3 \ -c coolbears.c # build coolbears-driver and link it to coolbears.o gcc -std=c99 -pedantic -Wall -Wextra -ftrapv -ggdb3 \ -o coolbears-driver coolbears-driver.c \ coolbears.o ./coolbears-driver
The coolest bear is Kevin
If we access coolest->name we get:
coolbears-driver.c: In function ‘main’: coolbears-driver.c:11:62: error: dereferencing pointer to incomplete type ‘struct coolbear_t’ printf("The coolest bear is %s\n", getNameCoolBear( coolest->name ));
1.5.5 What is the preprocessor doing?
Let's use the -E flag to see what checkinput.c becomes
This output contains glibc headers for stdio.h and stdlib.h these should be under the GPLV3 (c) the Glibc project and GNU project.
If you want more preprocessor options checkout:
https://gcc.gnu.org/onlinedocs/gcc-5.2.0/gcc/Preprocessor-Options.html
# build checkinput.o gcc -E -std=c99 -pedantic -Wall -Wextra -ftrapv -ggdb3 \ checkinput.c > checkinput-preprocessor.c
It produces this file:
# 1 "checkinput.c" # 1 "/home/hindle1/projects/CMPUT201W20/2020-01/CMPUT201W20B2-public/week10//" # 1 "<built-in>" #define __STDC__ 1 #define __STDC_VERSION__ 199901L #define __STDC_HOSTED__ 1 #define __GNUC__ 7 #define __GNUC_MINOR__ 5 #define __GNUC_PATCHLEVEL__ 0 // lots of definitions # 1 "/usr/include/stdio.h" 1 3 4 # 24 "/usr/include/stdio.h" 3 4 #define _STDIO_H 1 // Start of STDIO_H // ... extern int printf (const char *__restrict __format, ...); extern int sprintf (char *__restrict __s, const char *__restrict __format, ...) __attribute__ ((__nothrow__)); // LOTS OF STDIO.H // LOTS OF STDLIB.H # 1016 "/usr/include/stdlib.h" 3 4 # 1 "/usr/include/x86_64-linux-gnu/bits/stdlib-float.h" 1 3 4 # 1017 "/usr/include/stdlib.h" 2 3 4 # 1026 "/usr/include/stdlib.h" 3 4 # 5 "checkinput.c" 2 # 9 "checkinput.c" void checkInput(int err) { if (!err || err == # 10 "checkinput.c" 3 4 (-1) # 10 "checkinput.c" ) { printf("\nInvalid input!\n"); exit(1); } } return 0; }
1.5.6 Parameterized Macros
As we just demonstrated Macros generate code. So we can make compile functions that generate code. These functions run at compile time and generate code that is compiled by C.
#include <stdio.h> #include <stdlib.h> #include <stdbool.h> // RELU is a rectified linear unit.

That's interesting, but be aware that x is not a value. It is a set of tokens.

- Easy bugs!
So why doesn't this work?
#include <stdio.h> #include <stdlib.h> #include <stdbool.h> // if checkinput is true then you have an error #define CHECKINPUT(scanfReturn) ( scanfReturn == EOF || !scanfReturn ) int main() { int myInt = 0; if (CHECKINPUT(scanf("%d", &myInt))) { printf("Invalid input!\n"); exit(1); } printf("My int: %d\n", myInt); }

My int: 6 My int: 7 Invalid input! exit was 1 Invalid input! exit was 1 Invalid input! exit was 1
gcc -E -std=c99 -pedantic -Wall -Wextra -ftrapv -ggdb3 \ checkinputmacro.c > \ checkinputmacro-expanded.c
Let's look at the output:
#define CHECKINPUT(scanfReturn) ( scanfReturn == false || scanfReturn == EOF) # 8 "checkinputmacro.c" int main() { int myInt = 0; if (( scanf("%d", &myInt) == # 10 "checkinputmacro.c" 3 4 0 # 10 "checkinputmacro.c" || scanf("%d", &myInt) == # 10 "checkinputmacro.c" 3 4 (-1) # 10 "checkinputmacro.c" )) { printf("Invalid input!\n"); exit(1); } printf("My int: %d\n", myInt); }
I'll clear it up for you
#define CHECKINPUT(scanfReturn) ( scanfReturn == false || scanfReturn == EOF) int main() { int myInt = 0; if (( scanf("%d", &myInt) == 0 || scanf("%d", &myInt) == (-1))) { printf("Invalid input!\n"); exit(1); } printf("My int: %d\n", myInt); }
See? 2 scanfs instead of 1. Great. So macros will copy your tokens, not your values. They are meta-functions and not real functions.
How do we fix? We assign the result once!
#include <stdio.h> #include <stdlib.h> #include <stdbool.h> // if checkinput is true then you have an error // horrible and bad style don't do this at home! static int __ret; #define CHECKINPUT(scanfReturn) (__ret = scanfReturn, (__ret== EOF || !__ret )) int main() { int myInt = 0; if (CHECKINPUT(scanf("%d", &myInt))) { printf("Invalid input!\n"); exit(1); } printf("My int: %d\n", myInt); }

1.6 Makefiles
I am sick to death of all these shell scripts!
Look at the assignments 1 shell script per question and they mostly say the same things.
Programmers uses build systems to manage compiling and linking large programs. They often do not use shell scripts or batch files directly.
Makefiles allow you to use make to build your program. Make is declarative, dependency based build system.
Makefiles are full of rules for building files.
file-you-want-to-build: dependency1.c dependency2.o dependency3.o
gcc -o file-you-want-to-build dependency1.c dependency2.o dependency3.o
^^^ There is a tab character before the gcc
To build file-you-want-to-build you type:
make file-you-want-to-build
make
1.6.1 Basic Makefile
We're going to use the coolbears source code from before.
Instead of this:
# build coolbears.o gcc -std=c99 -pedantic -Wall -Wextra -ftrapv -ggdb3 \ -c coolbears.c # build coolbears-driver and link it to coolbears.o gcc -std=c99 -pedantic -Wall -Wextra -ftrapv -ggdb3 \ -o coolbears-driver coolbears-driver.c \ coolbears.o ./coolbears-driver
The coolest bear is Kevin
# this just runs a command but ensures it is built # first directive runs by default # usually you should but put the top level build directive here run: coolbears-driver ./coolbears-driver # just a shell command # build an object file coolbears.o: coolbears.c gcc -std=c99 -pedantic -Wall -Wextra -ftrapv -ggdb3 \ -c coolbears.c # build an executable coolbears-driver: coolbears-driver.c coolbears.o gcc -std=c99 -pedantic -Wall -Wextra -ftrapv -ggdb3 \ -o coolbears-driver coolbears-driver.c \ coolbears.o # clean is idiomatic for remove object files and executables clean: rm -f coolbears.o coolbears-driver
let's run it. Normally make just runs Makefile. But if you have your own makefiles you should use the -f option with make.
make -f Makefile.coolbears clean make -f Makefile.coolbears coolbears.o make -f Makefile.coolbears coolbears-driver make -f Makefile.coolbears run
rm coolbears.o coolbears-driver || echo nothing to delete gcc -std=c99 -pedantic -Wall -Wextra -ftrapv -ggdb3 \ -c coolbears.c gcc -std=c99 -pedantic -Wall -Wextra -ftrapv -ggdb3 \ -o coolbears-driver coolbears-driver.c \ coolbears.o ./coolbears-driver # just a shell command The coolest bear is Kevin
Or we could just do this:
# I am making clean just to clear out the executables and object files make -f Makefile.coolbears clean make -f Makefile.coolbears run
rm coolbears.o coolbears-driver || echo nothing to delete gcc -std=c99 -pedantic -Wall -Wextra -ftrapv -ggdb3 \ -c coolbears.c gcc -std=c99 -pedantic -Wall -Wextra -ftrapv -ggdb3 \ -o coolbears-driver coolbears-driver.c \ coolbears.o ./coolbears-driver # just a shell command The coolest bear is Kevin
OR we could do this!
# I am making clean just to clear out the executables and object files make -f Makefile.coolbears clean make -f Makefile.coolbears
rm coolbears.o coolbears-driver || echo nothing to delete gcc -std=c99 -pedantic -Wall -Wextra -ftrapv -ggdb3 \ -c coolbears.c gcc -std=c99 -pedantic -Wall -Wextra -ftrapv -ggdb3 \ -o coolbears-driver coolbears-driver.c \ coolbears.o ./coolbears-driver # just a shell command The coolest bear is Kevin
Ha it does the same thing!
What if I run make again?
# I am making clean just to clear out the executables and object files make -f Makefile.coolbears
./coolbears-driver # just a shell command The coolest bear is Kevin
It just uses the old object files.
# if I remove the executable it'll rebuild only the executable rm coolbears-driver make -f Makefile.coolbears
gcc -std=c99 -pedantic -Wall -Wextra -ftrapv -ggdb3 \ -o coolbears-driver coolbears-driver.c \ coolbears.o ./coolbears-driver # just a shell command The coolest bear is Kevin
# if I remove the object files it'll build the whole thing rm *.o make -f Makefile.coolbears
gcc -std=c99 -pedantic -Wall -Wextra -ftrapv -ggdb3 \ -c coolbears.c gcc -std=c99 -pedantic -Wall -Wextra -ftrapv -ggdb3 \ -o coolbears-driver coolbears-driver.c \ coolbears.o ./coolbears-driver # just a shell command The coolest bear is Kevin
Personally I would've preferred if assignments were done this way.
1.6.2 DRY Makefile
DRY means DON'T REPEAT YOURSELF.
Let's make a makefile that is easier to use and less prone to errors by repeating text.
Instead of this:
# this just runs a command but ensures it is built run: coolbears-driver ./coolbears-driver # just a shell command # build an object file coolbears.o: coolbears.c gcc -std=c99 -pedantic -Wall -Wextra -ftrapv -ggdb3 \ -c coolbears.c # build an executable coolbears-driver: coolbears-driver.c coolbears.o gcc -std=c99 -pedantic -Wall -Wextra -ftrapv -ggdb3 \ -o coolbears-driver coolbears-driver.c \ coolbears.o # clean is idiomatic for remove object files and executables clean: rm -f coolbears.o coolbears-driver || echo nothing to delete
We're going to automate our Makefile a little more with variables.
You can make a variable in a makefile by going VARNAME=some string of stuff LISTNAME=item1 item2 item3 item4 SCALARNAME="SCALAR VALUE"
# common arguments for GCC CFLAGS= -std=c99 -pedantic -Wall -Wextra -ftrapv -ggdb3 # Common compiler CC=gcc # you might call these OBJECTS instead BUILDABLES=coolbears.o coolbears-driver # this just runs a command but ensures it is built run: coolbears-driver ./coolbears-driver # just a shell command coolbears.o: coolbears.c $(CC) $(CFLAGS) \ -c coolbears.c # build an executable coolbears-driver: coolbears-driver.c coolbears.o $(CC) $(CFLAGS) \ -o coolbears-driver coolbears-driver.c \ coolbears.o # clean is idiomatic for remove object files and executables clean: rm -f $(BUILDABLES)
let's run it. Normally make just runs Makefile. But if you have your own makefiles you should use the -f option with make.
make -f Makefile.coolbears.dry run
./coolbears-driver # just a shell command The coolest bear is Kevin
1.6.3 Idiomatic GCC Makefile
Make knows a lot about C. Make comes with default rules that will call your compiler for you as long as CFLAGS and CC are properly set!
This means it knows how to make an executable.
It knows how to make an object file. It just needs to know the dependencies.
You can reuse this makefile as well!
# common arguments for GCC CFLAGS= -std=c99 -pedantic -Wall -Wextra -ftrapv -ggdb3 # Do you need your math lib? Put it here this is the linking libraries # variable LDLIBS=-lm # Common compiler CC=gcc OBJECTS=coolbears.o coolbears-driver.o EXEC=coolbears-driver BUILDABLES=$(OBJECTS) $(EXEC) # this just runs a command but ensures it is built run: $(EXEC) ./$(EXEC) # just a shell command # We don't even need to specify how to make coolbears.o # try commenting and uncommenting this line # coolbears.o: coolbears.c # build an executable # coolbears-driver: coolbears-driver.c coolbears.o # # this would work too # coolbears-driver: coolbears-driver.o coolbears.o $(EXEC): $(OBJECTS) # clean is idiomatic for remove object files and executables clean: rm -f $(BUILDABLES)
let's run it. Normally make just runs Makefile. But if you have your own makefiles you should use the -f option with make.
make -f Makefile.coolbears.idiomatic clean make -f Makefile.coolbears.idiomatic run
rm coolbears.o coolbears-driver.o coolbears-driver || echo nothing to delete nothing to delete gcc -std=c99 -pedantic -Wall -Wextra -ftrapv -ggdb3 -c -o coolbears-driver.o coolbears-driver.c gcc -std=c99 -pedantic -Wall -Wextra -ftrapv -ggdb3 -c -o coolbears.o coolbears.c gcc coolbears-driver.o coolbears.o -lm -o coolbears-driver ./coolbears-driver # just a shell command The coolest bear is Kevin
1.6.4 Special Macro Vars
- $@ the target file name
- $< the first dependency
- $? new dependencies that have changed
- $^ all dependencies
- $* target suffix
OBJECTS=example.txt 1.txt 2.txt 3.txt run: example.txt echo $@ $< $* cat example.txt example.txt: 1.txt 2.txt 3.txt echo First Dependency $< echo Target $@ echo New Deps $? echo All Deps $^ echo target suffix $* cat $^ > example.txt 1.txt: echo $@ > $@ 2.txt: echo $@ > $@ 3.txt: echo $@ > $@ clean: rm $(OBJECTS) || echo all good

- Implicit Rules
Here's an example of implicit rules. Of how we convert 1 file to another implicitly much like how Make hands C compilation.
############################### Implicit rules ############################### # Convert a .tex file to a .pdf %.pdf: %.tex $(ALLDEPS) latexmk -pdf $(LATEXMK_OPTS) $* # Convert SVGs to PDFs # Requires Inkscape %.pdf: %.svg inkscape -b white -t -T --export-ignore-filters --export-pdfs=$@ $< # Convert EPSs to PDFs # epstopdf(1) is often bundled with TeX distributions %.pdf: %.eps epstopdf $< # Automatically crops the margins of a PDF. %-crop.pdf: %.pdf pdfcrop $<
1.6.5 Can we lint and valgrind with our makefiles?

1.6.6 .PHONY
Hazel says:
It is also often useful to have a rule that removes the compiled code so that you can easily compile your program from scratch. This is useful when you change your Makefile. We can add a phony rule named clean so that when we run “make clean” on the command line it removes all the compiler outputs: s-expr, s-expr.o, and main.o:
.PHONY: clean clean: rm -f s-expr s-expr.o main.o
This tells make:
“clean” is not an actual file that will be made, instead we should run the recipe for “clean” everytime we make “clean”.
“clean” doesn’t have any input files that will change the output (there is nothing after the colon :)
When we make “clean” we will remove the files s-expr, s-expr.o, and main.o.
1.6.7 Makefile help
The GNU Manual is pretty good

1.6.8 Useful Tool! asan and usan
Google made some static analysis tools to detect issues!
(From chefmax of Google (2020) https://github.com/google/sanitizers/wiki/AddressSanitizer )
Address sanitizer detects:
- Use after free (dangling pointer dereference)
- Heap buffer overflow
- Stack buffer overflow
- Global buffer overflow
- Use after return
- Use after scope
- Initialization order bugs
- Memory leaks
I've been telling y'all to use it in the discussion forum. It's like valgrind but it does different things and has nice output.
How do you use it?
With clang or gcc add the argument
-fsanitize=address -fsanitize=undefined
For address sanitization or undefined santitization.
If you want more options check out https://gcc.gnu.org/onlinedocs/gcc/Instrumentation-Options.html
- ./arrayoob.c
Sanitize ./arrayoob.c with address!
gcc -std=c99 -pedantic -Wall -Wextra -ftrapv -ggdb3 -fsanitize=address -o array_oob ./array_oob.c echo 33 | ./array_oob 2>&1 || echo it crashed
How big? 32768 32769

"I sat in the back of the car and felt the tears rolling down my face. I hadn't cried for years but, on the way home, I couldn't stop. The tears kept coming. I can't even tell you if the streets were thick with traffic or as empty as I was on the inside. It was killing me."
Steven Gerrard cried for hours that day because he knew Liverpool had blown his best chance of winning the Premier League title. And to make it worse for the skipper, it was Gerrard who had slipped two years ago today against Chelsea which meant Manchester City would go on to win the league. Tottenham haven't blown the title like the Reds did, it will hurt, but not as much as it would have hurt Gerrard who knew this was his last ever chance. Nevertheless, the Merseyside club made some big mistakes the following season and Spurs can learn from it.
The biggest crime that Brendan Rodgers made was he sold his best player. In fairness to the northern Irishman, he didn't have much choice. Luis Suarez was one of the best players in the world and belonged to one of the best teams in the world. Not a team that he dragged from seventh to second. Not to mention the Uruguayan wanted to leave the previous summer to join Arsenal, but the captain at the time, Gerrard, persuaded him to play one more year in the hope Barcelona or Real Madrid would come calling the following season. And that's exactly what happened. Now Tottenham don't have a Luis Suarez, but they do have some top players that some big European clubs might be interested in. Harry Kane has scored more than 20 goals a season in consecutive campaigns and with top strikers few and far between now across Europe, European juggernauts will certainly be keeping an eye on him. Dele Alli has just won the Young Player of the Year award and at 20-years-old, he has plenty of time to improve. Toby Alderweireld, Eric Dier, and Christian Eriksen have all had impressive seasons and may be tempted by lucrative offers elsewhere. Of course, Spurs are no strangers to selling their best players and don't necessarily need to learn from Liverpool in this situation they just need to learn from themselves. While the likes of Erik Lamela, Eriksen, and Nacer Chadli have shown that they do have some value, Paulinho, Roberto Soldado, Etienne Capoue and Vlad Chiriches did not represent worthy Gareth Bale money. It's not easy to keep a player like Bale, especially if you're not in the Champions League, but now they do have European football and the cash that comes with it, there's no reason to sell a Kane, an Alli, or an Eriksen cheaply. The most important factor in all this, however, could be keeping hold of their manager and not necessarily the players. Mauricio Pochettino, as quoted by Sky Sports, said: "I've always said that I would be pleased to join a great club like PSG. "Come to Paris? I hope so. It is true that it would please me. It's part of my dreams. I try to watch all their matches, especially in the Champions League." That's worrying for Spurs fans. Hopefully, for their sake, he's just trying to increase the monetary benefits of a new contract, but if he is thinking of moving, players like Eriksen might decide against signing a new contract and move with him. Essentially, Pochettino is Tottenham's Luis Suarez and they must not let him get away.
It sounds simple, but there is always a temptation to bulk buy when you've had a successful season. Daniel Levy might have dollar signs flashing in his eyes right now, but even he knows that splashing the cash recklessly isn't going to help. The Bale money wasn't used effectively in most cases, even if a few have shown their ability this season. Now is the time to purchase in areas where they could be vulnerable. The problem with what Liverpool did after they finished second two years ago, was that they tried to bulk a squad that needed quality in many areas. Buying seven, eight or nine players isn't going to be easy to integrate. Pochettino proved last summer how building the team bit by bit can slowly make you great. They need to do the same again, provide cover for Dier and Kane, purchase another attacking player who can compete with Alli, Eriksen or Lamela and maybe a centre-half. No more, though, buy some Champions League quality to keep the squad hungry, and don't unsettle them. Levy needs to be confident now that Pochettino knows what he's doing. Trying to penny pinch over Saido Berahino last summer could have cost them dearly if Kane got injured. Sign a centre forward early and let the Argentinian manager spend on the areas he needs to improve, otherwise, he might not stick around. Spurs might have to be careful with their spending anyway with the new stadium being built so reckless spending shouldn't be a problem. The main thing, however, is for the north London club to not feel too disappointed on missing out on the title and strive to go again. They weren't expected to win the league and they're not expected to next season. They should be motivated more than ever to go one better next year.

Adding new parameters
All parameters in Zoltan should be set and accessed through the parameter
setting routines. To add a new parameter to an existing method, you
need to do the following:
-
In the source code for the desired method, search for the place where
the static array of parameters is defined. It will look something like:
static
PARAM_VARS Method_params[] = { ... }. Add a line with the name
of the new parameter, a pointer to the variable you want to associate (usually
NULL), and its type.
-
In the method source code, bind the parameter to a local variable through
Zoltan_Bind_Param.
Make sure you do this before Zoltan_Assign_Param_Vals
is
invoked.
-
Update the parameter function for the method in question. This routine
is typically called Zoltan_Method_Set_Param. This
routine checks if a given string is a valid parameter for that method.
It may also verify the values.
When you add a new method to Zoltan, you also need to:
-
Write a parameter function for your method that checks whether a given
string and value is a valid parameter pair for your method. See Zoltan_RCB_Set_Param
in rcb/rcb.c for an example.
-
Let your method access the parameters via Zoltan_Bind_Param
and
Zoltan_Assign_Param_Vals.
-
Change the parameter function array in params/set_params.c to include
your parameter function. Simply add a new entry to the static array that
looks like: static ZOLTAN_SET_PARAM_FN * Param_func[] = {...}.
-
Make sure your method uses the key
parameters in Zoltan correctly.
One useful convention is to put your method routine and your corresponding
parameter function in the same source file. This way you can define the
parameters in a static array. This convention eliminates the risk
of bugs caused by duplicate declarations (that are, incorrectly, not identical).
